Top quality remote control single beam or girder European style type electric overhead traveling crane

Top quality remote control single beam or girder European style type electric overhead traveling crane

1. Product  Description

European single girder overhead crane based on bringing in and assimilating foreign advanced technology, this type of crane takes modular design theories as guidance, uses modern computer technology as means, introduces optimized and reliable design methods, Which is a new type of crane made by employing import configuration, new material and technology and has features in light-weight, generalizing energy-conservation and environmental protection, maintenance-free and high technology content design, production, and inspection carry out the last issued relevant national standard, equivalently adopts some foreign criteria including FEM, DIN and IEC.

Compared with the general QD bridge crane, its weight is reduced by about 15-30%. The maximum wheel pressure is reduced by about 10-35%, which can the requirements of crane for factory building structure and reduce production cost. As the core component of the driving mechanism, reducer gear pair with the hard tooth surface and high accuracy, together with steel reel forged wheel and variable-frequency speed regulating system, which makes this type of crane become renewal product of traditional general bridge crane and applied in the industry of machinery production, assembling petrochemicals, warehouse logistics, electric power construction, paper making and railways

The main beam employs a bias-rail box-type structure and connects with the end beam by a high-strength bolt ensuring easy transportation.

Traveling mechanisms of crane and trolley adopt Europe three-in-one drive form, the harden gear face reducer has good performances in compact structure, low noise, no oil leakage and long service lite

As using a new compact trolley and high-strength material, it has small overall dimension and lightweight compared with traditional crane, which can decrease the height of factory building and reduce the cost

The modular design has a short design period and high generalization, which can improve the utilization of components

With compact structure, low clearance, small dimension and large application scope, it can improve production efficiency

Full variable-frequency control runs steadily without any impaction. Running with heavy load at low speed and light load at high speed, it can save energy and reduce consumption.

2. Some main paramters 

3. Mechanical parts

1.Single welding box girder, beam deflection with DIN/FEM standard

Steel Material: Chinese standard Q235B and Q345B

Trolley rail is made of high strength hot rolled flat steel (16 Mn)

Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster

The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine

The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate

Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail.

Both side of all the steel plate of crane are pretreatment by pretreatment production line,

Sand blasting– Primer spray–Primer drying. Eliminate the innerstress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality.

2. Steel plate cutting adapt whole sets Messer CNC plasma cutting machine from Germany, very fast cutting speed, little deformation, High precision,  Deviation could be controlled within 1mm, it insure the raw material at high quality standard and can reach top level in the industry.

3. The welding of main beam adapt high efficiency and intelligent welding robot, Henan Mine Crane Co.,LTDare No.1 enterprise who adapt this high technology machine. The welding joint inside of the main beam adapt advanced MAG welding, adapt Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adapt automatic submerged-arc fillet welding machine.

4. The welding of main beam adapt radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position

5. The welding of end beam adapt double gun gantry submerged arc welding, highly welding quality ensure the stable quality of the crane effectively.

6. Adapt the steel plate rolling drum and wireless steel tube, Henan Mine Crane Co.,LTDhas a set of steel plate rolling drum producing and processing line which is industry-leading level. From pre-bending by 1250t press machine, to Edge rolling by three-roller plate roll, at last the longitudinal joint and circumferential joint of drum are welded by automatic welding center and drum processed by heavy duty CNC horizontal machine tool.

7. The wheel and wheel axle and treating by high efficiency quenching and tempering, it can eliminate the internal stress effectively and ensure the processing precision,

The trolley frame, drum, and bogie frame and related big welding structure are treated by Annealing in the natural gas annealing furnace to ensure the Machining accuracy after welding. Henan Mine Crane Co.,LTDhave car bottom  natural gas annealing furnace, the furnace chamber inside size (length*width*heigh) is 10000mmx4000mmx4000mm, this annealing furnace can satisfy the Stress-Relieving annealing treatment after welding for the trolley frame, drum, bogie frame, balance beam, spreader and all kinds of welding structure on the crane, Only Henan Mine Crane Co.,LTD has this ability in China Crane Hometown.

8.Henan Mine Crane Co.,LTD has top advanced processing and manufacturing equipment and processing technology in the crane industry all over China, at the same time, Henan Mine Crane Co.,LTD take the head in achieve the best and better management, best and better manufacturing, Try the best to ensure the Henan Mine Crane Co.,LTD product quality and satisfy the demand of customer.
